Botox on just one side: Doctor injects half of husband’s face to show 'shocking' before-and-after

A Vancouver-based dermatologist, Dr Katie Beleznay, board-certified in both Canada and the US demonstrated how Botox works by injecting only one side of her husband Ben’s face. The controlled experiment showed, in real time, how neuromodulators soften lines, relax specific muscles and subtly change symmetry. Her video demystified a treatment often associated with extremes, offering a clear, practical look at its real effects.
